AVMATRIX TB-C41 SDI Video Grabber

Four 3G-SDI inputs in one compact desktop unit change the way a laptop or compact workstation can ingest camera feeds. AVMATRIX TB-C41 targets crews that need dependable SDI capture without moving to a full rackmount system: studio ingest, flypack production, live event recording, replay capture, remote contribution, or multi-source monitoring beside a vision mixer. Through its dual ultra-speed ports, the box moves data at up to 40 Gb/s, so four HD signals can be brought into the computer with the throughput expected in broadcast and streaming environments.

The signal side is built for established SDI infrastructure. The AVMATRIX TB-C41 accepts 4× SD/HD/3G-SDI inputs with support up to 1080p60, handles embedded audio at 48 kHz / 24-bit, and works with REC.601 and REC.709 colour spaces. For acquisition, it supports lossless formats including YUY2 and RGB; the SDI path itself is specified at 8-bit 4:2:2 YUV. That makes it a practical choice for ingest from PTZ cameras, shoulder cameras, studio cameras, switcher auxiliaries, replay servers, or routed SDI outputs feeding recording, streaming, logging, or QC stations.

Connectivity goes beyond simple capture. A DisplayPort 1.4 output lets the operator add a local reference screen, while the USB 3.1 Gen2 port supports peripherals such as keyboard and mouse on the same station. Daisy chaining helps in mobile rigs where every computer port matters, and PD support up to 60 W can simplify cabling in compact edit desks or engineering benches. In practice, that means fewer external adapters around a laptop during on-site productions, esports stages, worship installs, or temporary corporate streaming sets.

Its platform support fits production reality: Windows and Linux compatibility, DirectShow/V4L2 integration, and software support covering OBS, vMix, XSplit, VLC, VirtualDub, VidBlaster, Wirecast and more. Active cooling is included for continuous 24/7 duty, which matters once a capture box is left running through long rehearsals, conference sessions, overnight records, or always-on studio feeds. For teams building a reliable multi-channel SDI capture point around a modern laptop-class host, the AVMATRIX TB-C41 brings broadcast connectivity, practical port layout, and stable long-hour operation in one unit.
